Effects of elevated temperature on juvenile Coho salmon and benthic invertebrates in model stream communities

Creator:: Iverson, Ronald Albert
Abstract:: Juvenile coho salmon (Oncorhynchus kisutch (Walbaum)) and aquatic invertebrates were subjected to experimentally increased, but naturally fluctuating, temperatures in a model stream channel. Coho of the 1969, 1970, and 1971 year classes were reared in the heated model stream and in an unheated control stream, both located at the Oak...

Habitat factors affecting pronghorn use of playas in south central Oregon

Creator:: Good, James Ronald
Abstract:: Pronghorn (Antilocapra americana) use of four playas (intermittent lakebeds) on Hart Mountain National Antelope Refuge (NAR) in south central Oregon was studied during the summers of 1974 and 1975. Percent canopy cover of playa vegetation, plant phenology, percent desiccated vegetation, soil moisture, available surface water and pronghorn use of range...

Biology of juvenile sockeye salmon resident in Chignik River, Alaska

Creator:: Iverson, Ronald Albert
Abstract:: The life history of juvenile sockeye salmon (Oncorhynchus nerka) resident in Chignik River, Alaska, represents a departure from the lacustrine, pelagic existence typical of juveniles of this species. For this reason, the distribution, relative abundance in different parts of the river, growth, and upstream and downstream movements of juvenile sockeye...

An evaluation of attempts to reestablish the sea otter in Oregon

Creator:: Jameson, Ronald James
Abstract:: During the summers of 1970 and 1971 a total of 95 sea otter (Enhydra lutris) were shipped to Oregon from Amchitka Island, Alaska. The 1970 shipment consisted of 31 otter which were to be released on the southern Oregon Coast near the town of Port Orford. Two of these animals...

Life history and evolutionary adaptation of Pacific salmon and its application in management

Creator:: Wevers, Mary Jo
Abstract:: An approach to understanding and managing anadromous salmon, steelhead, and sea-run cutthroat trout (Oncorhynchus spp.) based on life history and evolutionary adaptive capacities of species and stocks is presented. Species, stocks, and local populations are viewed as systems that are continuously adapting to changing environmental conditions. They have the potential...

Using Spatial Capture-Recapture to Estimate Density of Roosevelt Elk in Western Oregon

Creator:: Nelson, Jennifer E.
Abstract:: Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...

Systematics, variation, distribution, and biology of lampreys of the genus Lampetra in Oregon

Creator:: Kan, Ting Tien
Abstract:: Based on the number of velar tentacles and the form of longitudinal lingual laminae found in Lampetra (Entosphenus) t. tridentata and its closely related forms, the taxon Entosphenus should not be considered as a genus as commonly adopted, but, along with the taxa Lethenteron and Lampetra, should be regarded as...
